Last Contact with Pioneer 10

January 23, 2003

The last successful contact was made with the spacecraft Pioneer 10, one of the most distant man-made objects in the universe. Pioneer 10 is heading in the direction of the star Aldebaran in the constellation Taurus at roughly 2.6 AU per year. If Aldebaran had zero relative velocity, it would take Pioneer 10 about 2 million years to reach it.
